Mathematical Simulation of the Kinetics of Supercritical Fluid-Extraction Regeneration of a Heterogeneous Catalyst

A mathematical model that describes the kinetics of the extractional regeneration of a heterogeneous catalyst by a solvent, including that in its supercritical state, has been proposed. A comparison of the results of numerical and real experiments reveals their qualitative compliance over the entire...

Description
Summary:A mathematical model that describes the kinetics of the extractional regeneration of a heterogeneous catalyst by a solvent, including that in its supercritical state, has been proposed. A comparison of the results of numerical and real experiments reveals their qualitative compliance over the entire time range of the process, as well as the quantitative agreement between them within the time range that corresponds to the high saturation of the catalyst with deactivating compounds.
